Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.

aFe Large Bore-HD exhaust systems are constructed from mandrel-bent 409 stainless steel tubing with high-quality band clamps and OE-style bayonet hangers. They use factory mounting locations to provide a quick, hassle-free installation. Also included with many of these diesel systems is a massive wrinkle-black powdercoated or polished 304 stainless steel tip with a laser-cut stainless steel aFe power badge.

aFe Large Bore-HD exhaust systems are the perfect combination of performance, fit, and value and feature:
• Leak-free 360 degree sealing
• Stable pipe location in high-vibration and high-heat conditions
• Bayonet tips hold hanger bushings in place for an OE-style fit
• Large diameter tubing provides maximum flow
• Smooth bends for low turbulence, increased horsepower and torque, and lower exhaust gas temperatures (EGTs)
• Slash-cut tips with intercooling vents reduce EGTs at the tailpipe (most applications)
• Available in DPF-back, cat-back, turbo-back, and downpipe-back configurations (varies by model)
• Select systems include dual outlets and exhaust tips

Note: Some of these systems are "Race Only" products sold solely for competition use. Their use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state, and federal laws.
